This method is implemented as a ^ (bitwise XOR) operation on the two sets’ raw values.
import Swiftprotocol OptionSet : RawRepresentable, SetAlgebraA type that presents a mathematical set interface to a bit set.
protocol FixedWidthInteger : BinaryInteger, LosslessStringConvertible where Self.Magnitude : FixedWidthInteger, Self.Magnitude : UnsignedInteger, Self.Stride : FixedWidthInteger, Self.Stride : SignedIntegerAn integer type that uses a fixed size for every instance.
mutating func formSymmetricDifference(_ other: Self) Removes the elements of the set that are also in the given set and adds the members of the given set that are not already in the set.
init() Creates an empty option set.
mutating func formIntersection(_ other: Self) Removes all elements of this option set that are not also present in the given set.
mutating func formUnion(_ other: Self) Inserts the elements of another set into this option set.
